E430-16
Alloy 430 is designed to weld materials of similar chemical composition as well as overlay on carbon steels. The undiluted weld metal is ferritic, but with the dilution from mild or low alloy steel, it could become martensitic. Therefore, preheating and interpass temperatures of 300°F (150°C) during welding are recommended.
